Jupiter occulted the star a couple hours later as the Sun was rising. Look closely and you can see it become more twinkly in the moments before it disappears, a glimpse of Jovian seeing conditions from my backyard on Earth.

Jupiter was in the line of sight between us and the magnitude 7.9 star HD 61660 on October 13th, appearing as an interloper among the Galilean Moons. It's an orange star 25x more luminous than the Sun and 660 light years away. Europa had a very close pass from home.

Titan casting its shadow on Saturn on August 3rd, 2025. Tethys is also transiting just above the rings, but they were blocking the view its shadow.

Neptune and Triton on September 19th, 2025. Look carefully and you'll notice the subtle gradient from brighter in the south to darker in the north.
